WASM debug issue (nvwgf2umx.dll)

Hi there!


My question #1:

- run Visual Studio

- build wasm

- MSFS > Build Package

- Visual Studio > Debug > Attach to Process... Attach

- select FlightSimulator.exe


I got the folllowig:

And a bunch of these messages in VS Output:

Exception thrown at 0x00007FFAFF217814 (nvwgf2umx.dll) in FlightSimulator.exe: 0xC0000005: Access violation reading location 0x000002C49BD80250.

Exception thrown at 0x00007FFAFF217A57 (nvwgf2umx.dll) in FlightSimulator.exe: 0xC0000005: Access violation reading location 0x000002C49BD80010.


Some simple gauges from SDK Samples do not cause this error.


My question #2:

How to use "Edit And Continue" in Visual Studio when wasm debug?



MSFS 1.29.30.0, MSFS SDK 0.20.5.0, Visual Studio 2019 Version 16.11.23


Thanks for any help.

Eugene

Hello @fsx360

We would need your wasm module and ideally the source code to debug this issue.

Check section 3 here to provide content privately: How to report a bug or crash - MSFS DevSupport (flightsimulator.com)

Sylvain

@FlyingRaccoon getting the same problem here. Only difference is for me it's another .pbd file that I'm told cannot be found. To give some more information: I have the VS Wasm Debugger Extension installed but don't know how to activate/use it yet. @fsx360 do you also have that extension installed without using it?

Sometimes I am able to debug a few steps before this happens.

Did you add the -AllowDebugger flag into your Steam's FlightSimulator Properties window?
